HYDROCABIBON-MOTOR.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed May 28, 1917. Serial No. 171,495.

cation.

This invention relates to hydrocarbon motors, and more particularly to an improved arrangement and disposition of the cooling and gas distribution passages.

One of the objects of this invention is to provide a motor having a detachable cylinder head and a jacketed gas intake conduit, with improved means for assembling and connecting these various parts.

Another object of this invention is to provide an improved arrangement for cooling the cylinder and its head, and then heating the gas induction pipe with the same circulating medium.

Another object of this invention is to provide a hydrocarbon motor with improved means for carrying the cooling medium from the cylinder jacket, through its acketed head, and over the gas induction pipe and finally discharging it to a cooling device such as a radiator.

These, and vaniois other objects, will, more clearly appear from the following description, taken in connection with the accompanying drawings, which form a part of this specification, and in which:

Figure 1 is a from; end elevation, with portion ll broken away. of a V-type hydrocarbon motor, embody ng a preferred form of my invention;

Fig. 2 is a perspective view of a flexible sleeve for connecting the head jacket and the gas intake conduit acket; and i F ig, 3 is a )erspective view of a combined inelosing and clamping sleeve for the connection illustrated in Fig. 2.

Referring to the dranings, ll) illustrates motor base or crank "use on which are urrangh! in V relation pair of cylinder blocks ll.

llach ol' the blocks is pm k dcd with a cooling jacket 12 having an intake port 13 preferably connected by flexible conduit: 14 with the discharge pm'l 15 of a centrir'ugai type circulating pump 16, which in turn is provided with an inlet port 17. The cylinder jackets 12 are rovided with outlet ports 18 I and the eylin ers are provided with valve controlled gas intake ports 19.

Heads 20 provided with cooling jackets 21 are arranged with their intake ports 22 in register with the cylinder jacket outlet ports 18 and are then adjustably connected as by bolts 23 to the cylinder blocks 11 with a yielding packing gasket 24therebetween.

A gas induction pipe 25 of inverted U form may be arranged between the cylinderblocks detachably connected as by bolts 26 and pipes 27 in position with the orts at the outer end of each of its branches 1n register with the cylinder gas intake ports 19. A cargureter 28 may be detachably connected as ductibn pipe intake port 30.

It will be noted that the induction pipe is provided with a jacket 31 having laterally extendinv arms in the end of each of which is formed a nipple 32 and inlet ports-33 which are adapted to be joined by a flexible sleeve 34, preferably of rubber to a nipple 35 and outlet port 36 of the head jacket 21. The rubber connections ma then be coricealed, and its opposite ends tightly clam d into position by means of a split meta ic sleeve 36, which is arranged over-the eonnector 34 with its lugs 37 drawn to r,

in any well known manner as by b0 tv 39. It will be noted that formed adjacent each cnd of the sleeve 36 are circumferentiall extending inturned depressions 138i whic will tend to bind the opposite ends of the connecting sleeve 34 on the adjacent nipples 33 and 35.

With the described arran ement it will be noted that the cooling me ium will be led into the cylinder jacket 12 of each of the blocks through the intake ports 13 and after circulating through these 'ac-kets, will be conducted through the head jacket 21, discharged therefrom through the flexible connections 34 to each of the branches of the conduit jacket, and after passing over the conduit and heatiu the same, it will be discharged through tie outlet port-39 from which it may be carried in any well knownbolts 29 in position over the gas ininduction pipe to the cylinder jacket through the detachable head, under wide variations of manufacture. This I am en abled to do by means of the flexible and adj ustable connections which are provided.

While I have described and will specifically claim what I deem to he a pre erred embodiment of my invention, it will be obvious to those skilled in the art that various modifications and changes may 'be made without departing from the spirit and scope hereof.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In an internal combustion engine, the combination with a cylinder having a gas intake opening and a detachable head having a water outlet opening, of a combination gas and water conduit having rigid connection with one of said openings and a flexible connection with the other of said openings.

2. In an internal combustion engine, the combination with a cylinder having a. gas intake opening and a detachable head having a water outlet opening, of a coinhlnation gas and water conduit having connections with said openin and one of which connections is fiexibi.

In an internal combustion engine, the combination with a jacketed cylinder having a gas intake opening and a jacket outlet opening, of a combination gas and water conduit having a rigid connection with one of said openings and a flexible connection with the other of said openings.

4. In an internal combustion. engine, the combination with a cylinder having a gas inlet port, and a cooling jacket having a water outlet port, of a combination gas and water conduit detachably connected with said water outlet and gas intake ports, one of the connections aforesaid being flexible.

5. In an internal combustion engine, the combination with a c linder having a gas inlet port, and a coo ing jacket having a water outlet port, of a combination gas and water conduit detachably connected with said Water outlet and gas intake ports, one of the connections aforesaid being flexible and the other rigidw 6. In an internal combustion engine, the combination with two c linders arranged adjacent one another, and each of which is provided with a gas intake port, and with a cooling jacket having a water outlet port, of a combination gas and water conduit detachably connected with the water outlet ports of both said cylinders, and also with the gas intake ports of both said cylinders, one of the connections aforesaid between said conduit and each of said cylinders being flexible. r
